Title: Optical fibre illuminating device employing optical fibres
IPC: F21S10/00
Filed: 1979-07-17
Abstract: This invention relates to an optical illumination device composed of optical fibre members. In the basic arrangement of a known optical illumination device one of the respective ends of the optical fibre members is opposed to a light source, with a filter disposed therebetween and movable across the path of incident light, the movement of the filter causing the other ends of the optical fibre members to illuminate with colors. The optical illumination device of the invention is characterized in that a number of optical fibre members 1 are arranged in a substantially planar form and fixed in position to form a sheet-like portion 4, one surface of which is suitably broken to provide a substantially planar light-leaking section 7. <IMAGE>

Title: Optical fibre having lens-shaped end
Inventor: BRICHENO TERRY
IPC: G02B6/255
Filed: 1981-12-01
Abstract: It is desirable to be able to provide a lens at the end of an optical fibre to mode-match an asymmetrical optical waveguide or a laser into a symmetrical optical fibre. This may be effected by heating the fibre in an electric arc to soften it and pulling the fibre until it breaks. Then the end may be arc- polished to give the end a suitable profile for a lens. The thus formed fibre end is then polished into a V-groove (6) in e.g. a glass block (4), which is vibrated lengthwise as indicated by the arrow (8). An abrasive slurry (7) may be placed in the groove to facilitate polishing. Finally the fibre end may be arc-polished to correct its shape. <IMAGE>

Title: Method and apparatus for deboning fish
IPC: A22C25/16
Filed: 1981-12-03
Abstract: A method of deboning beheaded fish of the herring and/or mackerel type conveyed at their backs with the head end foremost comprises effecting a preparatory incision of the tail portion of the fish along both sides of the spine as far as the region of the back radii before the deboning cut. The tail portion is for this purpose driven onto filleting knives (2) which are freed only during the passing of this portion of the fish, controlled by setting means (15) which pivots guides (6) away from the knives when abdominal cavity end passes setting means so that the spine can be cut out economically in the tail portion of the fish. The subsequent deboning cut is effected by knives (5) which effect relatively inclined incisions starting from immediately above the ribs, which are spread apart together with the belly lobes, and converging to meet in the region of the dorsal fin. This cut stops when abdominal cavity end arrives and raises element (16) so filleted tail portion passes over knives (5). <IMAGE>
